The present invention relates to electrical connector means and more particularly to means for interconnecting a plurality of electrical cables with each other.

it is customary to interconnect the electrical conductors or wires in electrical cables with the electrical conductor in another cable or electronic equipment by means of mating connectors. The connectors normally contain sets of registering contacts such as pins and sockets that electrically engage when the connectors are mated. One of the problems frequently encountered in making a satisfactory connector is sealing the junction between the two connectors whereby moisture, dust, etc. is prevented from interfering with the operating of the contacts. One means of scaling is to provide various forms of resilient gaskets consisting of an elastomer, such as rubber. Although such gasket materials are generally satisfactory for providing moistureproof junctions, they are usually electrically nonconductive and accordingly, interfere with the electrical interconnection between the mating connectors.

Under some circumstances it is highly desirable to provide an electrically conductive shield in or around the cable to prevent any form of electromagnetic energy producing stray or spurious currents in one or more conductors in the cables. It is to be noted that the effectiveness of the shielding is depen dent upon all portions of the shield being electrically interconnected with each other and with ground by means of a continuous low resistance path. Since the gasket material is electrically nonconductive it has been found extremely difficult, if not impossible, to maintain a high degree of coupling between the shielding on both sides of the connectors. This problem is particularly acute when the stray electromagnetic energy is of a higher frequency and tends to travel entirely on an electrically conductive surface as contrasted with a low frequency or DC signal that travels through the material. it will thus be seen the foregoing connectors have not been entirely satisfactory for all applications, and particularly in those requiring a high degree of shielding against high frequency electromagnetic energy.

The present invention provides means for overcoming the foregoing difficulties. More particularly the present invention provides means for sealing a connector against the entrance of moisture, dirt, etc. while still forming a continuous electrically conductive path for eliminating spurious signals and particularly those signals which are produced by high frequency electromagnetic energy. in the single embodiment of the present invention disclosed herein this is accomplished by providing a sealing gasket adapted to be utilized between a pair of mating connectors so as to seal the mating surfaces. This gasket includes a resilient elastomer, such as rubber, for sealing the junction. In addition an electrically conductive rim is provided around the resilient portion in a position whereby it is compressed between the mating electrically conductive outer portions of the connectors. When the two connectors are tightly secured together the resilient elastomer is highly compressed and seals the mating surfaces on the connectors. in addition the resilient material tends to flow radially outwardly and thereby expand the metal rim into more intimate electrical contact with the-connector housing.

These and other features and advantages of the present invention will be readily apparent from the following detailed description of one embodiment thereof wherein-like reference numerals refer to like parts and wherein;

FIG. I is a side view, with portions thereof being broken away, of a connector utilizing one form of the present invention;

FIG. 2 is a side view, on a greatly enlarged scale, with a portion thereof broken away of the seal utilized in the connector of FIG. I.

Referring to the drawings in more detail the present invention is particularly adapted to be embodied in a sealing gasket [0 for use in sealing a pair of connectors 12 and 14 for interconnecting two electrical cables 16 and 18. It should be understood, however, that this gasket 19 may also be used for connecting a cable or any type of electrical equipment to any other electrical equipment.

The electrical cables 16 and 18 are of a conventional variety and includes a bundle 24 of independent electrical conductors or wires 20. Normally each of these wires 20 is surrounded by a layer of insulating material 22 whereby the wires 20 are electrically isolated from each other. The entire bundle 24 of wires 20 is, in turn, surrounded by a suitable cover to maintain the wires 20 together. This cover may be electrically insulating material. The cover may also or alternatively include an electrically conductive shield 28 that completely surrounds the entire bundle 24 of wires 20. This shield 28 may be of any conventional variety. However, in the present instance it is of the woven variety containing a plurality of metal strands. In the event this shield 28 is exposed to any stray electromagnetic fields electrical currents will be created in the shield 28. These currents will tend to travel along the shield 28 without being coupled into any of the independent wires in the bundle 24. The end of the shield 28 may include a coupling, such as a rigid or semirigid collar 36. This coupling is attached to the shield 28 by soldering or any other suitable means or maintaining it in intimate electrical contact with the shield 28. The shield 28 and collar 36 tenninate short of the ends of the bundle 24 whereby the individual conductors have exposed ends.

The ends of the cables 16 and 18 extend through a neck 30 or 32 into the side of the connector l2 and 14 whereby the exposed ends of the individual wires 20 extend into the interior of the connectors. Fastening means, such as a threaded nut 34, may be provided on the end of the cables 16 and 18 for being threaded onto the necks 30 and 32 and drawing the coupling 36 against the end of the neck 30 or 32. This will tightly secure the cable 16 or 18 to the connector 12 or 14 and provide a sealed junction.

in addition the end of the shielding 28 will be maintained in intimate electrical contact with the connector 12. Accordingly a continuous unbroken electrical path will always be maintained between the shielding 28 and the connectors 12 and 14. if any stray currents are created in the shielding 28 and are circulating thereon they will also circulate into and around the connectors 12 or 14.

The actual structure of the two mating connectors 12 and 14 may be of any desired variety. By way of example the two connectors 12 and 14 include separate generally cylindrical housings 38 and 40 having mating ends 42 and 44. Each of the housing 38 and 40 includes a smooth cylindrical passage 46 or 48 which are aligned with each other when the two ends 42 and are mated.

in order to secure the two housing 38 and 40 together any suitable fastening means 50 may be provided. The present fastening means 50 includes a detent 52 carried by a collar 54 which is free to slide on the barrel 56 of the housing 38. A second collar 58 is rotatably mounted on the housing 38 and threadably engages the first collar 54. By rotating the second collar 58 the detents 52 may be moved axially relative to the housing 38.

The connector 14 includes a plurality of detents 60 positioned to engage the first detents $2 and secure the connectors 12 and I4 together. These detents 42 are preferably on the ends of spring fingers 62 whereby the two connectors 12 and 14 may be mated by pushing them together until the fingers 62 snap over the ends of detents 52. Similarly they may be separated by pulling them until the fingers 62 snap over the detents 52.

To lock the connectors l2 and 14 together a sleeve 64 may be provided on the housing 38 for movement inside of the spring finger detents 62 by means of the pushrod 66. This prevents the detent fingers 60 being deflected radially inwardly and over the detents 52. Once the detents 52 and 60 are locked together by sleeve 64 the collar 58 may be rotated to pull the collar 54 axially inwardly and draw the connector housings 38 and 40 together whereby the ends 42 and 44 are insured of mating. To release the connectors 12 and 14 the sleeve 64 is retracted to permit the finger detents 60 being sprung over the detents 52.

The exposed ends of the individual conductors or wires 20 are equipped with contacts 68 and 70 that mate with a complimentary contact on the corresponding wire in the other bundle. These contacts may be of any desired variety, however, in the present instance they are of the so-called pin and socket variety. The pin contacts 68 include an enlarged barrel and a reduced end or shank that forms a pin 72. The bare end of the conductor 20 is inserted into the center of the barrel and secured in position by soldering, crimping, etc. The socket contacts 70 include an enlarged barrel having an axial passage that forms a socket 74 for receiving the pin 72. The opposite end of the barrel includes an opening for receiving the bare end of the wire 20.

In order to maintain the contacts 68 and 70 in position one or more inserts 76, 78, 80 and 82 may be disposed in the passages 46 and 48 in the two housings 38 and 40. In the present instance two separate inserts 76-78 and 80-82 are provided in each passage 46 and 48 respectively. These fit snugly into their respective passages 46 and 48 and engage a radial flange on the ends 42 and 44 of the housing 38 and 40 whereby they are prevented from passing through the end. A suitable keeper 84 and 86 is threaded into the passages to engage the back of the inserts and clamp them against the shoul ders. The various inserts include a plurality of passages 88 into which the contacts 68 and 70 are positioned.

Before the pairs of block 76-78 or 80-82 are assembled and mated a suitable snap fastener 90 may be provided in the passages 88 for locking the contacts in position. After the inserts 76, 78, 80 and 82 are in position and the contacts 68 and 70 are secured to the ends of the wires 20 they may be inserted through the passages 88 until the barrels have passed into the snap fastener 90 and the connectors are locked into position.

It can be appreciated the two connectors 12 and 14 may be mated and secured together as described above. At the time they are mated the pin contacts 68 will slide into the socket contacts 70 and thereby establish and maintain electrical continuity between the various wires in the two cables 16 and 18.

Before securing the two connectors 12 and 14 together the gasket may be placed on one of the connectors whereby the junction between the connectors 12 and 14 will be sealed. The gasket 10 includes a main body 92 that is essentially a disc or a relatively flat thin member. The body 92 includes a resilient material or elastomer such as a rubber which can be relatively easily deformed. One side of the body 92 has a plane surface 93 effective to fit tightly and snugly against the end of the end the insert 78. The periphery 96 extends radially outwardly around the entire body 92. This extends over the end 42 when the body 92 is fitted against the insert 78 and registers with the end 42. The periphery 96 will thereby be compressed between the two ends 42 and 44.

A plurality of passages 98 are provided through the body 92 so as to register with the pins 72 projecting from the insert 78. The inside diameters of these passages 98 are somewhat smaller than the outside diameters of the pins 72. This provides a tight fit between the pins 72 and the passages 98 whereby the gasket 10 will stay put on the pins 72 and snug against the end of the insert 78. Also it will tend to improve the sealing action.

The opposite side of the body 92 includes a plurality of projections I00. These are positioned substantially concentric about the passages 98 so as to form a raised shoulder 102 about each of the pins 72 when the gasket 10 is positioned against the insert 78. These shoulders 102 are adapted to engage the end of the insert 80 when the two connectors l2 and 14 are initially mated. When the collar 58 is turned to tighten the two connectors 12 and 14 the resilient body 92 is compressed between the two inserts 78 and 80 and a moistureproof, dustproof etc. seal is formed. This seal will thereby protect the electrical contacts 68 and 70.

When high frequency energy is incident upon the cables 16 and 18 and/or connectors 12 and 13 correspondingly high frequency currents circulate in and around the shield 28 and the connectors 12 and 14. If all portions of the shield 28 and the connectors 12 and 14 are electrically connected together and to ground by a low impedance path very little, if any, of the signals will be coupled onto wires 20. It has been found that when the frequency approaches or exceeds a threshold level the passages 46 and 48 tend to act as a waveguide whereby the electromagnetic energy can be coupled through the connectors 12 and 14. This is effective to shunt this energy to ground without inducing spurious signals on the wires 20.

However. if the mating ends 42 and 44 are sealed by an electrically nonconductive material, such as the periphery 96, the space 104 between the ends 42 and 44 forms a very high impedance to high frequency signals that may be circulating on the surfaces of the passages 46 and 48. As a consequence the high frequency signals do not travel freely through the connectors whereby the overall grounding effect is greatly reduced and objectionable signals tend to be coupled onto one or more of the wires 20.

in order to avoid this difficulty an electrically conductive rim 106 may be provided around the periphery 96. In the present instance this rim 106 is a metal member which is folded into a U-shaped cross section having two convergent sides I08 and 110, as best seen in FIG. 2. The periphery 96 is disposed between the opposite sides of the rim I06 and maintains it on the body 92. The two sides I08 and 110 engage the two ends 42 and 44 and forms a low impedance path across the space I04 between the two parts of the connectors 12 and 14.

in order to use the present invention the gasket 10 is slipped over the pins 72 and forced against the insert 78. The periphery 96 now overlaps the end 42 and the electrically conductive rim 106 contacts the end 42. The two connectors 12 and I4 may be mated whereby the pins 72 extend into the sockets 74 and the detents 60 snap over the detents 52. The connectors 12 and 14 are now secured together and electrically conductive paths are provided between the various wires 20 in the cables 16 and 18. The sleeve 64 may then be moved inside of the detents and the collar 58 tightened. This will draw the two connectors 12 and 14 together.

in the drawing together process the shoulders I02 will first engage the insert and then the entire body 92 will be compressed between the inserts 78 and 80. At the same time the rim 106 will be in engagement with the two ends 42 and 44 whereby the rim 106 and the periphery 96 will be compressed therebetween. As the main body 92 is compressed in an axial direction between the inserts 78 and 80 it forms a highly effective leakproof seal. At the same time at least a portion of the material in the body 92 tends to flow radially outwardly toward and into the rim 106. This radial flow of the resilient material in the body 92 will be effective to expand the two sides 108 and 110 in an axial direction. To facilitate the flexing of the sides 108 and H0 in response to the various forces imposed thereon, a plurality of radial slots [12 may be provided in the sides M6 at several circumferential points. This action, in combination with the compressing of the rim 106 between the ends 42 and 44, will force the two sides I08 and H0 very firmly against the ends 42 and 44. As a consequence a very highly effective leakproof seal will be provided in the space 104 and a low impedance path will be maintained across the space 104.

it may be seen a low impedance path is formed from the shielding on the cable 16 all the way to the shielding on the cable 18. As a consequence any stray currents whether direct, high frequency or anywhere therebetween will be effectively grounded and prevented from being coupled to any of the conductors in the cables. The success of this grounding action is dependent to a considerable degree upon the effectiveness of the electrical contacts between the various mating surfaces having a low resistance.

Very frequently the various parts of the connector are made of lightweight materials, such as an aluminum alloy. All

materials and particularly these lightweight materials, tend to corrode and to some extend form oxide coatings having relatively high electrical resistances. As a consequence, if the grounding paths include mating corroded surfaces, the shielding action is degraded.

In order to avoid this difficulty it has been found desirable to provide a noncorroding material on the various mating surfaces. For example, on the ends of the neck 30 and the collar 36, as well as on the neck 32 and collar 34. Also the mating ends 42 and 44 of the housings 38 and 40 may be similarly protected.

Although these surfaces may be of any desired variety it has been found advantageous to provide a material such as a noble metal (i.e. gold, platinum, silver etc.) which does not corrode and provides an uncontaminated surface with a very low electrical resistance. A thin coating may be formed by plating, flashing, etc. the noble metal onto the surface. It has been found, however. the coating tends to wear through and/or become scored and scratched after a relatively small number of opening and closing cycles. Accordingly if the connector is to be opened and closed a large number of times it has been found desirable to provide a thicker more rugged ring of noble metal. A ring of considerable thickness can withstand a large amount of abuse without destroying the surface. The ring may be secured in position by any suitable means such as brazing, soldering, welding etc.

While only a single embodiment of the present invention is disclosed herein, it will be readily apparent to persons skilled in the art that numerous changes and modifications may be made thereto without departing from the scope of the invention. Accordingly, the foregoing disclosure and description thereof are for illustrative purposes only.
